Effect of Geriatric-Specific Trauma Triage Criteria on Outcomes in Injured Older Adults: A Statewide Retrospective Cohort Study.

ABSTRACT: To evaluate the effect on outcomes of the Ohio Department of Public Safety statewide geriatric triage criteria, established in 2009 for emergency medical services (EMS) to use for injured individuals aged 70 and older.Retrospective cohort study of the Ohio Trauma Registry.All hospitals in Ohio.Individuals aged 70 and older in the Ohio Trauma Registry from January 2006 through December 2011, 3 years before and 3 years after criteria adoption (N = 34,499).Primary outcomes were in-hospital mortality and discharge to home. Criteria effects were assessed using chi-square tests, multivariable logistic regression, interrupted time series plots, and multivariable segmented regression models.After geriatric criteria were adopted, the proportion of older adults qualifying for trauma center transport increased from 44% to 58%, but EMS transport rates did not change (44% vs 45%). There was no difference in unadjusted mortality (7.1% vs 6.6%) (P = .10). In adjusted analyses, subjects with an injury severity score (ISS) less than 10 had lower mortality after adoption (3.0% vs 2.5%) (odds ratio (OR) = 0.81, 95% confidence interval (CI) = 0.70-0.95, P = .01). Discharge to home increased after adoption in the adjusted analysis (OR = 1.06, 95% CI = 1.01-1.11, P = .02). There were no time-dependent changes for either outcome.Although the proportion of older adults meeting criteria for trauma center transport substantially increased with geriatric triage criteria, there were no increases in trauma center transports. Adoption of statewide geriatric triage guidelines did not decrease mortality in more severely injured older adults but was associated with slightly lower mortality in individuals with mild injuries (ISS <10) and with more individuals discharged to home. Improving outcomes in injured older adults will require further attention to implementation and use of geriatric-specific criteria.

Project description:BackgroundThe American College of Surgeons Committee on Trauma sets national targets for the accuracy of field trauma triage at ≥95% sensitivity and ≥65% specificity, yet the cost-effectiveness of realizing these goals is unknown. We evaluated the cost-effectiveness of current field trauma triage practices compared with triage strategies consistent with the national targets.Study designThis was a cost-effectiveness analysis using data from 79,937 injured adults transported by 48 emergency medical services agencies to 105 trauma and nontrauma hospitals in 6 regions of the western United States from 2006 through 2008. Incremental differences in survival, quality-adjusted life years (QALYs), costs, and the incremental cost-effectiveness ratio (costs per QALY gained) were estimated for each triage strategy during a 1-year and lifetime horizon using a decision analytic Markov model. We considered an incremental cost-effectiveness ratio threshold of <$100,000 to be cost-effective.ResultsFor these 6 regions, a high-sensitivity triage strategy consistent with national trauma policy (sensitivity 98.6%, specificity 17.1%) would cost $1,317,333 per QALY gained, and current triage practices (sensitivity 87.2%, specificity 64.0%) cost $88,000 per QALY gained, compared with a moderate sensitivity strategy (sensitivity 71.2%, specificity 66.5%). Refining emergency medical services transport patterns by triage status improved cost-effectiveness. At the trauma-system level, a high-sensitivity triage strategy would save 3.7 additional lives per year at a 1-year cost of $8.78 million, and a moderate sensitivity approach would cost 5.2 additional lives and save $781,616 each year.ConclusionsA high-sensitivity approach to field triage consistent with national trauma policy is not cost-effective. The most cost-effective approach to field triage appears closely tied to triage specificity and adherence to triage-based emergency medical services transport practices.

Project description:Objective: Older adults make up a rapidly increasing proportion of motor vehicle occupants and previous studies have demonstrated that this population is more susceptible to traumatic injuries. The CDC recommends that patients anticipated to have severe injuries (Injury Severity Score [ISS] ≥ 16) be transported to a trauma center. The recommended target rate for undertriage is ≤ 5% and for overtriage is ≤ 50%. Several regression-based algorithms for injury prediction have been developed in order to predict severe injury in occupants involved in a motor vehicle collision (MVC). The objective of this study to was to determine if the accuracy of regression-based injury severity prediction algorithms decreases for older adults.Methods: Data were obtained from the National Automotive Sampling System - Crashworthiness Data System (NASS-CDS) from the years 2000-2015. Adult occupants involved in non-rollover MVCs were included. Regression-based injury risk models to predict severe injury (ISS ≥ 16) were developed using random split-samples with the following variables: age, delta-V, direction of impact, belt status, and number of impacts. Separate models were trained using data from the following age groups: (1) all adults, (2) 15-54 years, (3) ≥45 years, (4) ≥55 years, and (5) ≥65 years. The models were compared using the mean receiver operating characteristic area under curve (ROC-AUC) after 1,000 iterations of training and testing. The predicted rates of overtriage were then determined for each group in order to achieve an undertriage rate of 5%.Results: There were 24,577 occupants (6,863,306 weighted) included in this analysis. The injury prediction model trained using data from all adults did not perform as well when tested on older adults (ROC-AUC: 15-54 years: 0.874 [95% CI: [0.851-0.895]; 45+ years: 0.837 [95% CI: 0.802-869]; 55+ years: 0.821 [95% CI: 0.775-0.864]; and 65+ years: 0.813 [95% CI: 0.754-0.866]). The accuracy of this model decreased in each decade of life. The performance did not change significantly when age-specific data were used to train the prediction models (ROC-AUC: 18-54 years: 0.874 [95% CI: 0.851-0.896]; 45+ years: 0.836 [95% CI: 0.798-0.871]; 55+ years: 0.822 [95% CI: 0.779-0.864]; and 65+ years: 0.808 [95% CI: 0.748-0.868]). In order to achieve an undertriage rate of 5%, the predicted overtriage rate by these models were 50% for occupants 15-54 years, 61% for occupants ≥ 55 years, 70% for occupants ≥ 55 years, and 71% for occupants ≥ 65 years.Conclusion: The results of this study indicate that it is more difficult to accurately predict severe injury in older adults involved in MVCs, which has the potential to result in significant overtriage. This decreased accuracy is likely due to variations in fragility in older adults. These findings indicate that special care should be taken when using regression-based prediction models to determine the appropriate hospital destination for older occupants.

Project description:ObjectiveTo examine sociodemographic predictors of trauma center (TC) transport of severely injured older adults.Data sourcesThe data source was the Healthcare Cost and Utilization Project, New York Inpatient Database (2014).Study designThis study was a secondary analysis of injured older adults. Key sociodemographic variables were age, gender, race/ethnicity, median household income, and primary payer. Confounding variables were injury severity, geographic location, number of chronic conditions, and injury mechanism. The outcome variable was TC transport.Data collection/extraction methodsThe database was filtered on the following criteria: age =/> 55 years, primary diagnosis of injury (International Classification of Diseases, 9th Revision, Clinical Modification [ICD-9-CM], 800.0-957.9, excluding poisoning, late effects, and interfacility transfers), admitted to an acute care hospital in New York.Principal findingsRecords of 33 696 patients were included. Multivariate logistic regression analysis revealed that all variables were statistically significant predictors of TC transport except primary payer. Predictors of TC transport were as follows: higher injury severity (OR 2.1, CI 1.79-2.46; 3.39, CI 2.85-4.05); Asian/Pacific and Hispanic race/ethnicity (OR 2.51, CI 1.92-3.27; OR 1.1, CI 0.86-1.42), highest median household income (OR 1.24, CI 1.01-1.52), high population density (OR 1.32, CI 1.12-1.55; OR 3.2, CI 2.68-2.83), and vehicle crashes (OR 3.39, CI 2.79-4.11). Predictors of non-TC transport were as follows: older age groups (OR 0.92, CI 0.76-1.11; OR 0.79, CI 0.64-0.96; OR 0.77, CI 0.63-0.95), females (OR 0.65, CI 0.57-0.74), Black and "other" race (OR 0.75, CI 0.0.56-1.0; OR 0.96, CI 0.77-1.20), lower median household income (OR 0.76, CI 0.62-0.93; OR 0.86, CI 0.71-1.05), low population density (OR 0.96, CI 0.67-1.36; OR 0.89, CI 0.53-1.51), and number of chronic conditions (OR 0.89, CI 0.87-0.91).ConclusionsSociodemographic factors are a source of disparity for access to TCs. Further research is needed to confirm bias and test bias reduction strategies. Comprehensive education and policies are needed to reduce disparities in access to trauma care.

Project description:BackgroundPre-hospital identification of major trauma in elderly patients is key for delivery of optimal care, however triage of this group is challenging. Elderly-specific triage criteria may be valuable. This systematic review aimed to summarise the published pre-hospital elderly-specific trauma triage tools and evaluate their sensitivity and specificity and associated clinical outcomes.MethodsMEDLINE and EMBASE databases were searched using predetermined criteria (PROSPERO: CRD42019140879). Two authors independently assessed search results, performed data extraction, risk of bias and quality assessments following the Grading of Recommendations, Assessment, Development and Evaluation system.Results801 articles were screened and 11 studies met eligibility criteria, including 1,332,300 patients from exclusively USA populations. There were eight unique elderly-specific triage criteria reported. Most studies retrospectively applied criteria to trauma databases, with few reporting real-world application. The Ohio Geriatric Triage Criteria was reported in three studies. Age cut-off ranged from 55 to 70 years with ≥ 65 most frequently reported. All reported existing adult criteria with modified physiological parameters using higher thresholds for systolic blood pressure and Glasgow coma scale, although the values used varied. Three criteria added co-morbidity or anti-coagulant/anti-platelet use considerations. Modifications to anatomical or mechanism of injury factors were used by only one triage criteria. Criteria sensitivity ranged from 44 to 93%, with a median of 86.3%, whilst specificity was generally poor (median 54%). Scant real-world data showed an increase in patients meeting triage criteria, but minimal changes to patient transport destination and mortality. All studies were at risk of bias and assessed of "very low" or "low" quality.ConclusionsThere are several published elderly-specific pre-hospital trauma triage tools in clinical practice, all developed and employed in the USA. Consensus exists for higher thresholds for physiological parameters, however there was variability in age-cut offs, triage criteria content, and tool sensitivity and specificity. Although sensitivity was improved over corresponding 'adult' criteria, specificity remained poor. There is a paucity of published real-world data examining the effect on patient care and clinical outcomes of elderly-specific triage criteria. There is uncertainty over the optimal elderly triage tool and further study is required to better inform practice and improve patient outcomes.

Project description:BackgroundStandardization in tools and documentation of child abuse and intimate partner violence have proven helpful in completely documenting injuries and suspected abuse among these populations. Similar tools do not yet exist for older adults and elder abuse.ObjectiveTo (1) use insights from experts to develop a tool to assist clinicians in appropriately and completely documenting physical findings in injured older adults for potential future forensic investigation of abuse or neglect and (2) to assess the feasibility of incorporating this tool into clinical practice.DesignTwo-phase, exploratory qualitative study. Phase 1: individual interviews with elder abuse experts from various specialties in medicine and criminal justice. Phase 2: focus groups with anticipated end users of the tool.ParticipantsPhase 1 telephone-based key informant interviews were conducted with 11 elder abuse experts (2 detectives, 3 prosecutors, 1 forensic pathologist, 2 geriatricians, and 3 emergency medicine physicians). Phase 2 focus groups were conducted among emergency medicine (n = 10) and primary care (n = 8) providers.ApproachKey informant interviews were conducted telephonically while the two focus groups were held in-person at an emergency medicine site in New York, NY, and a primary care site in Los Angeles, CA.Key resultsExperts agreed that medical providers' documentation of geriatric injuries is usually inadequate for investigating alleged elder abuse/neglect. They highlighted elements needed for forensic investigation: initial appearance before treatment is initiated, complete head-to-toe evaluation, documentation of all injuries (even minor ones), and documentation of pertinent negatives. Several noted the value of photographs to supplement written documentation. End users identified practical challenges to utilizing a tool, including the burden of additional or parallel documentation in a busy clinical setting, and how to integrate it into existing electronic medical records.ConclusionA practical tool to improve medical documentation of geriatric injuries for potential forensic use would be valuable. Practical challenges to utilization must be overcome.

Project description:ImportanceTrauma registries are the primary data mechanism in trauma systems to evaluate and improve the care of injured patients. Research has suggested that trauma registries may miss high-risk older adults, who commonly experience morbidity and mortality after injury.ObjectiveTo compare injured older adults who were included in with those excluded from trauma registries, with a focus on patients with serious injuries, requiring major surgery, or dying after injury.Design, setting, and participantsThis cohort study included all injured adults 65 years and older transported by 44 emergency medical services agencies to 51 trauma and nontrauma centers in 7 counties in Oregon and Washington from January 1, 2011, to December 31, 2011, with follow-up through December 31, 2012. Record linkage was used to match emergency medical services records with state trauma registries, state discharge databases, state death registries, and Medicare claims. Data were analyzed from August to November 2018.ExposuresInclusion in vs exclusion from a trauma registry.Main outcomes and measuresMortality up to 12 months, including time to death and causes of death.ResultsOf 8161 included patients, 5579 (68.4%) were women, and the mean (SE) age was 82.2 (0.10) years. A total of 1720 older adults (21.1%) were matched to a trauma registry record. Seriously injured patients not captured by trauma registries ranged from 18% (7 of 38 patients with abdominal-pelvic Abbreviated Injury Scale score of 3 or greater) to 80.0% (1792 of 2241 patients with extremity Abbreviated Injury Scale score of 3 or greater), while 68 of 186 patients requiring major nonorthopedic surgery (36.6%) and 1809 of 2325 patients requiring orthopedic surgery (77.8%) were not included in trauma registries. Of patients with serious injuries or undergoing major surgery missed by trauma registries (range by injury and procedure type, 36.0% to 57.1%), 36.4% (39.3% when excluding serious extremity injuries and orthopedic procedures) were treated at trauma centers, particularly level III through V hospitals. When registry and nonregistry groups were tracked over 12 months, 93 of 188 in-hospital deaths (49.5%) and 1531 of 1887 total deaths (81.1%) occurred in the nonregistry cohort.Conclusions and relevanceIn their current form, trauma registries are ineffective in capturing, tracking, and evaluating injured older adults, although mortality following injury is frequently due to noninjury causes. High-risk injured older adults are not included in registries because of care in nontrauma hospitals, restrictive registry inclusion criteria, and being missed by registries in trauma centers.

Project description:BackgroundUrgency triage in the emergency department (ED) is important for early identification of potentially lethal conditions and extensive resource utilization. However, in older patients, urgency triage systems could be improved by taking geriatric vulnerability into account. We investigated the association of geriatric vulnerability screening in addition to triage urgency levels with 30-day mortality in older ED patients.DesignSecondary analysis of the observational multicenter Acutely Presenting Older Patient (APOP) study.SettingEDs within four Dutch hospitals.ParticipantsConsecutive patients, aged 70 years or older, who were prospectively included.MeasurementsPatients were triaged using the Manchester Triage System (MTS). In addition, the APOP screener was used as a geriatric screening tool. The primary outcome was 30-day mortality. Comparison was made between mortality within the geriatric high- and low-risk screened patients in every urgency triage category. We calculated the difference in explained variance of mortality by adding the geriatric screener (APOP) to triage urgency (MTS) by calculating Nagelkerke R2 .ResultsWe included 2,608 patients with a median age of 79 (interquartile range = 74-84) years, of whom 521 (20.0%) patients were categorized as high risk according to geriatric screening. Patients were triaged on urgency as standard (27.2%), urgent (58.5%), and very urgent (14.3%). In total, 132 (5.1%) patients were deceased within a period of 30 days. Within every urgency triage category, 30-day mortality was threefold higher in geriatric high-risk compared to low-risk patients (overall = 11.7% vs 3.4%; P < .001). The explained variance of 30-day mortality with triage urgency was 1.0% and increased to 6.3% by adding the geriatric screener.ConclusionCombining triage urgency with geriatric screening has the potential to improve triage, which may help clinicians to deliver early appropriate care to older ED patients.
